"...open source advocates..."
Granted, there are more and less strident and more and less sensible ones. To his credit, +Bruce Byfield
is not strident, and (usually) sensible. Not so much this
time, I'm afraid.
However, there's a much greater level of tolerance for the "free software crazies"—and I would number folks like Roy Schestowitz and (yes, I'm gonna say it) Richard Stallman, as well as a strong strain of apologism, for Stallman, anyway, among the open source advocates, generally speaking...
None of this serves them well.
